Notes
Heterozygous mutant mice appear normal and are fertile. Homozygous mutant mice are runted (dwarfism) with a flat face and domed skull due to defects in cartilage development and delayed bone formation. The mutation appears to affect cranial bones derived from cartilage templates but not those from membranous ossification (J:52575). Collectively, the phenotypes are reminiscent of spondyloepiphyseal dysplasias.
